Ask any professional and they will tell you, 1 inch of water, per week is best. Every yard is different, due to soil, slope, and shade. Call a professional for sound advice. Your local County Agricultural office is also very knowledgeable.
I turn my sprinkler off every winter, is this good for my lawn?
Most people don’t realize that water during the winter is just as important as water during the summer, maybe more so . Humidity is much lower during the winter months. A strong 30 mph north wind can dry your lawn out as fast as a 100 degree day during the summer. We usually get more rain during the winter in North Texas, but not always. Monitor the weather forecast. Once a week watering is usually sufficient during winter months for a healthy spring lawn.
